I've read countless posts on these pedals without anyone mentioning the same installation issue that I've came across and this is actually costing me alot of $$ to repair so it might be informative to put out there for the benefit of all.

The problem comes from drilling the gas pedal and using the mounting screw that came with the pedals. I drilled two small hole to guide the insertion of the gas pedal screws (did not drill deep) and this caused damage to the electrical instruments/wiring that's found behind the lower half of the gas pedal. I did not insert these screws from strange points on the gas pedal that I did not already see anyone posting their pedal pictures did for their installations. In fact, when I saw K-Man's picture of his pedals, my screw locations are very similar to his.

Anyways, the first time I started the car after installing these pedals were the next morning so I had to wonder whether the strange symptoms were cause by these new pedals. Engine would rev to 1800 rpm at cold start and drop only to about 1000 shortly after. Everytime the clutch is depressed rpm would rev to about 1200 and it would return to 1000 when i releases clutch. When AC is turned on it would also cause rpm to rise. Without doubt, I brought the car back to the dealership and informed them about the new pedals i installed and whether the screws on the gas pedal could have been the cause. They assured me that wasn't it and went on to doing about 4+ days of investigation and I am now looking at a 3K bill when they finally realized that it is afterall, the pedal I had told them about since day one. Btw, no one else had similar issues??

Hopefully my experience will prevent this from happening to another fellow CS owner. Anyone is welcome to ask me about more details if you are curious about this.

Hmm...sorry this happened to you. Guess I'll take racing pedals off my mod list for now.

Thanks for the information. I have been thinking about this for a while but hadn't gotten to it. I too will delete that from my project list. Thanks again.

I don't like drilling extra holes unless I have to. I used 3M double-stick tape to install the dead pedal and gas pedal, and a few dabs of epoxy for the clutch and brake pedals. No holes, and can be removed without leaving holes.

I would not be happy for a dealership to ignor your initial diagnosis, spend a very long expensive time investigating, only to discover you were correct.

I would see if there is some room for negotiation on this as it appears to be cart blanch for a dealership to spend many hours to fix the most simple of tasks and just bill you for the time

Wow, that is VERY scary. I have some spare screws from my AWE pedal set and I'll measure and report back tonight how long they are.

I know Rennline has a gas pedal that completely replaces the stock unit. I wonder if anyone has removed the gas pedal and seen what wiring lurks under the bottom of it.

Thanks guys, and I do not intend to let them slap me with the 3K bill, that's outrageous.

Actually I love the way these pedals look so I am putting it right back on after I get my car back, with NO SCREWS this time. This is a small problem that can be easily prevented with alternative installation methods, you shouldn't have to scratch the idea from your mods list.

Keep us up to date Justin. I'm going to check my AWE's tonight to see if I can feel the bottom screw hitting anything.

You can get away with using tape on the gas pedal, but I would not do this for the brake pedal. There's nothing to damage on the other side of the brake and you never know when you have to stomp on that HARD.

Good luck.

Here is a pict of my AWE's installed. I really didn't have too much choice of a bottom screw location.

The top screw went behind a open circular area on the back of the gas pedal. Hard to describe, but if you feel the back of the gas pedal, you'll know what I mean.

Yes Pete you’re absolutely right, there is nothing to worry about with the clutch & brake and the drilled holes helps me secure the pedals real well. I also know exactly what you meant by the top screw on the gas pedal, I could feel the screw penetrating the back of the stock pedal a little so I know there is nothing behind it. However, by looking at your picture it would appear that my second screw on the gas pedal is probably an inch or so higher than yours. Will keep you guys posted on the actual related damage cost when I know it.

Justin - sorry you had this trouble. CS Jeff installed my Ruf pedals. I seem to remember him saying something about having to be careful about some wiring. Jeff checked with a Porsche tech friend of ours prior to installing and he tipped him off about the wires if I remember right. I'm sure he'll chime in. Any DIY project with our P-cars, he almost always checks with our tech buddy. They always give us a heads-up on something. The first time we do something, it's always interesting. The learning curve usually gets us. My first brake pad change was a doozie... the story is out here in caymanclub land.... The latest DIY Jeff did is kind of funny. Ask Jeff why one of his calipers no longer has "PORSCHE" on it...

Okay, got some update from the service manager. It appears that the screw was slightly pressing against the part (they used a fancy word that I can’t remember) that controls the thruster. Removal of the screw does not fix the problem because it is slightly stuck in that position so they had to open it and push it back. This is why I didn’t know if the screw was the problem, I had tried to remove it to see if it was causing it but it didn’t respond to that. This basically means that no replacement part was necessary to fix the problem, perhaps just half an hour of labor.

Service guy also said that a quarter inch long screw would have done the job to secure it, this might help those of you that would still like to secure the gas pedal with screws.

Cheers y'all.

I appreciate the warning that you are giving this community, Justin.
